Taw qhia

LoRaWAN Distance Detection Sensor yog dab tsi
Lub Dragino LDDS75 yog LoRaWAN Distance Detection Sensor rau Is Taws Nem ntawm Yam Kev daws teeb meem. Nws yog siv los ntsuas qhov kev ncua deb ntawm lub sensor thiab ib qho khoom tiaj tus. Lub ntsuas ntsuas qhov deb yog ib qho module uas siv ultrasonic sensing thev naus laus zis rau kev ntsuas kev deb, thiab qhov kub thiab txias tau ua haujlwm sab hauv los txhim kho kev ntseeg tau ntawm cov ntaub ntawv. LDDS75 tuaj yeem siv rau cov xwm txheej xws li kev ntsuas kab rov tav, ntsuas qib kua, kev tswj xyuas qhov chaw nres tsheb, qhov ze ze thiab pom qhov pom, cov thoob khib nyiab ntse tswj qhov system, neeg hlau tiv thaiv kev tiv thaiv, tsis siv neeg tswj, dej phwj tuaj, ntsuas dej hauv qab, thiab lwm yam.

Nws pom qhov kev ncua deb ntawm cov khoom ntsuas thiab lub sensor, thiab uploads tus nqi ntawm wireless rau LoRaWAN IoT Server.

LoRa wireless thev naus laus zis siv hauv LDDS75 tso cai rau cov cuab yeej xa cov ntaub ntawv thiab ncav cuag qhov ntev ntev ntawm cov ntaub ntawv-tus nqi. Nws muab ultra-ntev ntau kis spectrum kev sib txuas lus thiab kev cuam tshuam kev tiv thaiv kev tiv thaiv thaum txo qis kev noj tam sim no.
LDDS75 yog siv los ntawm 4000mA lossis 8500mAh Li-SOCI2 roj teeb; Nws yog tsim los siv ntev txog 10 xyoo *.
Txhua LDDS75 pre-loads nrog ib txheej ntawm cov yuam sij tshwj xeeb rau LoRaWAN kev sau npe, sau npe cov yuam sij no rau LoRaWAN server hauv zos thiab nws yuav pib txuas yog tias muaj kev pabcuam hauv network, tom qab fais fab tuag.

Configure LDDS75 los txuas rau LoRaWAN network

Nws ua haujlwm li cas
LDDS75 tau teeb tsa raws li LoRaWAN OTAA Class A hom los ntawm lub neej ntawd. Nws muaj OTAA yuam sij los koom nrog LoRaWAN network. Txhawm rau txuas LoRaWAN network, koj yuav tsum nkag mus rau OTAA cov yuam sij hauv LoRaWAN IoT server thiab lub zog ntawm LDDS75. Yog tias muaj kev pab cuam ntawm LoRaWAN network, nws yuav cia li koom nrog lub network ntawm OTAA thiab pib xa tus nqi sensor.
Yog tias koj tsis tuaj yeem teeb tsa OTAA cov yuam sij hauv LoRaWAN OTAA server, thiab koj yuav tsum siv cov yuam sij los ntawm lub server, koj tuaj yeem siv AT Commands los teeb cov yuam sij hauv LDDS75.

Cov lus qhia ceev txuas mus rau LoRaWAN server (OTAA)
Hauv qab no yog ib qho example rau kev koom nrog TTN LoRaWAN Network. Hauv qab no yog cov qauv network; peb siv LG308 ua LoRaWAN rooj vag hauv qhov example.

LDDS75 hauv LoRaWAN Network

LG308 twb tau teeb tsa los txuas rau TTN network, yog li qhov peb xav tau tam sim no yog teeb tsa TTN server.

Kauj ruam 1: Tsim ib lub cuab yeej hauv TTN nrog OTAA yuam sij los ntawm LDDS75.
Txhua LDDS75 raug xa nrog ib daim ntawv nplaum nrog cov yuam sij hauv lub neej ntawd, tus neeg siv tuaj yeem pom daim ntawv nplaum no hauv lub thawv. zoo li hauv qab no.

Rau kev sau npe OTAA, peb yuav tsum teeb tsa APP EUI / APP KEY / DEV EUI. Qee tus neeg rau zaub mov yuav tsis tas yuav teeb tsa APP EUI.
Nkag mus rau cov yuam sij no hauv LoRaWAN Server portal. Hauv qab no yog TTN screen txhaj tshuaj:
Ntxiv APP EUI hauv daim ntawv thov

Ntxiv APP YUAM thiab DEV EUI Kauj ruam 2: Fais fab ntawm LDDS75
Muab lub Jumper rau JP2 kom lub zog ntawm lub cuab yeej. (Qhov hloov yuav tsum tau teeb tsa hauv FLASH txoj haujlwm). Kauj ruam 3: LDDS75 yuav pib koom nrog TTN network. Tom qab koom nrog kev ua tiav, nws yuav pib xa cov lus rau TTN thiab koj tuaj yeem pom cov lus hauv vaj huam sib luag.

Uplink Nyiaj Thauj
LDDS75 yuav uplink payload ntawm LoRaWAN nrog rau hauv qab payload hom: Uplink payload suav nrog tag nrho 4 bytes. Cov ntaub ntawv roj teeb
Xyuas lub roj teeb voltage rau LDDS75.
Ex1: 0x0B45 = 2885mV
Ex2: 0x0B49 = 2889mV

Nyob deb
Tau qhov deb. Cov khoom sib txawv ntawm 280mm - 7500mm.
Rau example, yog tias cov ntaub ntawv koj tau txais los ntawm kev sau npe yog 0x0B 0x05, qhov kev ncua deb ntawm lub sensor thiab cov khoom ntsuas yog 0B05(H) = 2821(D) = 2821 mm.

Yog hais tias tus nqi sensor yog 0x0000, nws txhais tau tias system tsis ntes ultrasonic sensor. Yog tias tus nqi sensor qis dua 0x0118 (280mm), tus nqi sensor yuav siv tsis tau.

Txiav txim siab payload hauv Yam Network
Thaum siv TTN network, koj tuaj yeem ntxiv cov ntawv them nyiaj los txiav txim siab them nyiaj. Lub payload decoder muaj nuj nqi rau TTN nyob ntawm no:

AT + CFM	Ib qho	05	4
INTMOD	Ib qho	06	4

Examples
Set TDC
Yog tias payload = 0100003C, nws txhais tau tias teeb tsa END Node's TDC rau 0x00003C = 60(S), thaum hom code yog 01.
Payload: 01 00 00 1E TDC = 30S
Payload: 01 00 00 3C TDC = 60S
Rov pib dua
Yog tias payload = 0x04FF, nws yuav rov pib dua LDDS75
CFM
Downlink Payload: 05000001, Teem AT + CFM = 1 lossis 05000000, teeb AT + CFM = 0

Qhia cov ntaub ntawv hauv Mydevices IoT Server
Mydevices muab tib neeg tus phooj ywg interface los qhia cov ntaub ntawv sensor, thaum peb muaj cov ntaub ntawv hauv TTN, peb tuaj yeem siv Mydevices txuas rau TTN thiab pom cov ntaub ntawv hauv Mydevices. Hauv qab no yog cov kauj ruam:

Kauj ruam 1: Nco ntsoov tias koj lub cuab yeej programmed thiab txuas nrog lub network zoo nyob rau lub sijhawm no.
Kauj ruam 2: Txhawm rau teeb tsa Daim Ntawv Thov xa cov ntaub ntawv mus rau Mydevices koj yuav tsum tau ntxiv kev koom ua ke. Txhawm rau ntxiv Mydevices kev koom ua ke, ua cov kauj ruam hauv qab no:

Kauj ruam 3: Tsim ib tus account lossis nkag rau hauv Mydevices.

Kauj ruam 4: Nrhiav LDDS75 thiab ntxiv DevEUI. Tom qab ntxiv, cov ntaub ntawv sensor tuaj txog TTN, nws tseem yuav tuaj txog thiab qhia hauv Mydevices. Qhov taw qhia LED
LDDS75 muaj ib qho LED sab hauv uas yog los qhia cov xwm txheej ntawm lub xeev sib txawv.

Blink ib zaug thaum lub tshuab hluav taws xob qhib.
Cov cuab yeej kuaj pom lub sensor thiab flashes 5 zaug.

Hloov lub roj teeb
Koj tuaj yeem hloov lub roj teeb hauv LDDS75.Lub hom roj teeb tsis txwv ntev npaum li qhov tso zis ntawm 3v rau 3.6v. Ntawm lub rooj tsavxwm loj, muaj lub diode (D1) nruab nrab ntawm lub roj teeb thiab lub ntsiab Circuit Court. Yog tias koj xav siv lub roj teeb uas muaj tsawg dua 3.3v, thov tshem D1 thiab txiav ob lub ncoo ntawm nws kom tsis muaj vol.tage poob ntawm lub roj teeb thiab lub rooj tsavxwm loj.
Lub neej ntawd roj teeb pob ntawm LDDS75 suav nrog ER18505 ntxiv rau super capacitor. Yog tias cov neeg siv nrhiav tsis tau cov pob no hauv zos, lawv tuaj yeem nrhiav ER18505 lossis sib npaug, uas yuav ua haujlwm feem ntau. SPC tuaj yeem nthuav lub roj teeb lub neej rau kev siv ntau zaus (hloov lub sijhawm hloov tshiab hauv qab 5 feeb)

Siv AT Commands

Nkag mus rau AT Commands
LDDS75 txhawb AT Command teeb tsa hauv Tshuag firmware. Koj tuaj yeem siv USB rau TTL adapter txuas rau LDDS75 rau kev siv AT hais kom ua, raws li hauv qab no.
